Abstract

A stable austenitic alloy for cryogenic applications comprises (by weight per cent): carbon: 0.023 to 0.05; chromium: 9.00 to 10.00; manganese: 30.00 to 35.00; silicon: 1.3 to 2.5; nickel: 4.0 to 6.0; nitrogen: 0.15 to 0.25; molybdenum: 2.5 to 3.5; and vanadium: 0.4 to 0.6; balance iron and incidental and/or residual impurities. The alloy has a high yield strength at both cryogenic and room temperatures.
